| 摘 要： | 采用超滤设备对马铃薯淀粉生产过程中的废液进行循环浓缩，研究在室温、操作压力为0.16 MPa循环浓缩时，膜通量与料液中蛋白质的质量浓度之间的变化规律，得到马铃薯淀粉废液超滤浓缩过程中的传质方程，依据传质方程求出形成凝胶层的马铃薯蛋白质质量浓度为71.582 g/L；依据阻力模型理论，建立操作压力与膜通量的模型，并探讨不同操作压力区域对膜通量的影响。

| Abstract: | Ultrafiltration was used for concentrating potato starch wastewater. This study investigated the relationship
explore the between changes in membrane flux and protein concentration at room temperature and 0.16 MPa. The mass
transfer equation describing the ultrafiltration process was developed which indicated that the concentration (ρg) of potato
protein for forming a gel layer was 71.582 g/L. A model of membrane flux as a function of operating pressure based on the
resistance model theory was establishedwhich will be benefit for exploring the influence of different operating pressure on
membrane fluxunder. |
